Clinical Outcomes in AYAs (Adolescents and Young Adults) Treated with Proton Therapy for Uveal Melanoma: A Comparative Matching Study with Elder Adults. Cancers (Basel) 2023; 15:4652. [PMID: 37760619 PMCID: PMC10526519 DOI: 10.3390/cancers15184652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 09/13/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
OBJECTIVE The aim of this study was to compare the clinical outcomes of adolescents and young adults (AYAs) with those of elder adult patients treated with proton therapy (PT) for uveal melanoma (UM). MATERIAL AND METHODS A retrospective, comparative study was conducted in UM patients who underwent PT at the Ocular Oncology Unit of the Jules-Gonin Eye Hospital (University of Lausanne, Lausanne, Switzerland) and the Paul Scherrer Institute (PSI); (Villigen, Switzerland) between January 1997 and December 2007. Propensity score matching (PSM) was used to select for each AYA (between 15-39 years old) an elder adult patient (≥40 years) with similar characteristics. We assessed ocular follow-up, local tumor control, metastasis incidence, and overall and relative survival (OS and RS). Non-terminal outcomes were then compared between the two groups using competing risk survival analysis. RESULTS Out of a total of 2261 consecutive UM patients, after excluding 4 children (<15 years) and 6 patients who were metastatic at presentation, we identified 272 AYA patients and matched 270 of them with 270 elder adult patients. Before PSM, the AYA patients had a higher incidence of primary iris melanoma (4.0% vs. 1.4%; p = 0.005), while the elder patients were more likely to have other neoplastic diseases at presentation (9% vs. 3.7%; p = 0.004). Ocular outcomes and local tumor control were similar in both groups. Cumulative metastasis incidence for the AYA and elder adult groups was 13% and 7.9% at 5 years and 19.7% and 12.7% at 10 years, respectively, which was not significantly different between the groups (p = 0.214). The OS was similar in the two groups (p = 0.602), with estimates in the AYA and elder adult groups of 95.5% and 96.6% at 5 years and 94.6% and 91.4% at 10 years, respectively. However, the relative survival (RS) estimation was worse in the AYA group than the elder group (p = 0.036). CONCLUSION While AYAs treated with PT for UM have similar ocular outcomes and present the same metastasis incidence and OS as elder adults, their RS is worse than that in elder adults, when compared with the population in general.

Association between Subjective and Objective Assessment of Enucleation Outcome Depending on the Presence of an Orbital Implant in Patients with Uveal Melanoma. J Clin Med 2022; 11:jcm11082141. [PMID: 35456233 PMCID: PMC9024917 DOI: 10.3390/jcm11082141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 03/26/2022] [Accepted: 04/07/2022] [Indexed: 11/17/2022] Open
Abstract
We aimed to assess the cosmetic outcome of patients who underwent enucleation for uveal melanoma. The subjective assessment was based on a questionnaire, including four questions on postoperative cosmetic outcome. As part of the objective assessment, the following features were evaluated using a four-point scale: the symmetry of the upper eyelid sulcus, color matching between the prosthetic and healthy eye, prosthetic eye motility, and eyelid position. We enrolled 90 patients after enucleation (58 with and 32 without an orbital implant). The overall subjective assessment scores were 3.5/4 and 3.3/4 points in patients with and without an implant, respectively. The overall objective assessment scores were 3.3/4 and 2.3/4 in patients with and without an implant, respectively (p < 0.001). The cosmetic outcome was rated significantly higher by patients than by investigators (p < 0.05). There was no significant association between the overall subjective and objective assessment of the cosmetic outcome in any of the groups. Cosmetic outcome after enucleation for uveal melanoma was highly rated by patients. It was rated higher by patients than by investigators. The presence of an orbital implant was associated with higher objective assessment scores in terms of the symmetry of the upper lid sulcus, prosthetic eye motility, and eyelid position.

Abstract
Uveal melanoma (UM) is the most commonly diagnosed primary intraocular tumor in adults. Familial UM (FUM), defined as two or more family members diagnosed with UM, is rare and estimated at less than 1% of all UM. Currently, BAP1 is the only gene known to contribute significant risk for UM. In this study we aimed to estimate the frequency of BAP1 mutation in FUM and to characterize the family and personal histories of other cancers in these families. We identified 32 families with FUM, including seven families previously reported by our group. BAP1 mutation testing was carried out by direct sequencing of the coding exons and the adjacent untranslated regions of the gene. Germline deletion and duplication analysis of BAP1 was assessed by multiplex ligation-dependent probe amplification (MLPA). Germline BAP1 mutations were found in 6/32 (19%) families. No deletions or duplications were identified in any of the 24 samples tested by MLPA. Combined with published studies, the frequency of BAP1 mutations was 14/64 (22%) in FUM. FUM families without BAP1 mutations have distinct family histories with high rates of prostate cancer in first- and second-degree relatives. It is likely that additional genes conferring risk for FUM exist. It is important to understand key shared features of FUM to focus future research on identifying these additional tumor predisposition syndromes. Though BAP1 should be tested first in these families, FUM families without BAP1 mutation should be explored for additional predisposition genes. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND Uveal melanoma (UM) is the most common primary cancer of the eye in adults. About half of the patients are at risk of developing metastatic disease resulting in a poor clinical prognosis. Metastatic progression is strongly associated with loss of one chromosome 3 in the tumour (monosomy 3). The tumour suppressor gene BAP1 was found to be recurrently mutated in UM with monosomy 3. Familial UM is rare and amounts to about 0.6-6% of all patients with melanoma. However, BAP1 germline mutations have been identified in rare hereditary tumour syndromes, including cases with UM. One may assume that UM may be part of these hereditary conditions with predisposition to malignant cancers. METHODS The patients underwent complete ophthalmological workup and enucleation due to UM. Microsatellite analysis was performed to determine the chromosome 3 status of the tumours. Sanger sequencing of all coding exons of the BAP1 gene was performed in blood DNA of the patients. RESULTS Here we report on two family members (mother and son) diagnosed with UM. In both patients, a cosegregating BAP1 germline mutation (c.299 T>C) was found. The mutant BAP1 allele was retained in the tumour of the son showing monosomy 3. The son further developed urothelial carcinoma and liver metastasis, the mother was affected by the UM and cholangiocellular carcinoma. CONCLUSIONS [corrected] We detected a cosegregating BAP1 germline mutation in two family members with UM. This suggests that, consistent with a classic tumour suppressor model, carriers of damaging mutations in BAP1 are predisposed to UM. However, as BAP1 germline mutations have been found to cause other cancer syndromes as well, there must be other factors that decide about the type of tumour emerging from BAP1 inactivation.

Abstract
Primary intraocular neoplasms are tumors that originate within the eye. The most common malignant primary intraocular tumor in adults is uveal melanoma and the second is primary intraocular lymphoma or vitreoretinal (intraocular) lymphoma. The most common malignant intraocular tumor in children is retinoblastoma. Genetics plays a vital role in the diagnosis and detection of ocular tumors. In uveal melanoma, monosomy 3 is the most common genetic alteration and somatic mutations of BAP1, a tumor suppressor gene, have been reported in nearly 50% of primary uveal melanomas. The retinoblastoma gene RB1 is the prototype tumor suppressor gene-mutations in RB1 alleles lead to inactivated RB protein and the development of retinoblastoma. Immunoglobulin heavy chain (IgH) or T-cell receptor (TCR) gene rearrangement is observed in B-cell or T-cell primary vitreoretinal lymphoma, respectively. Other factors related to the genetics of these three common malignancies in the eye are discussed and reviewed.

Abstract
The specific genetic mechanisms responsible for the malignant behavior of uveal melanoma are not known. Unlike cutaneous melanoma, epidemiologic studies have not demonstrated a definitive germline form of uveal melanoma, though familial melanoma and racial predilections occur. Molecular cytogenetic characterization of uveal melanoma suggests that somatic deletions of chromosome 3 are associated with a worse prognosis. Microarray technology has been used to characterize uveal melanoma gene expression and may provide tests useful for determining prognosis. As an improved understanding of the cellular mechanisms used by uveal melanoma is gained, new opportunities to adapt or design therapeutic approaches may emerge.

Abstract
INTRODUCTION This study aimed to investigate the clinical profile of young patients with uveal melanoma treated in 1995-2002 in the Department of Ophthalmology, Jagiellonian University, Krakow, Poland. METHODS Retrospective case-control series. RESULTS Out of 800 patients with uveal melanoma treated between 1995 and 2002, there were 11 patients (1.4%) aged 20 or younger. The mean age of those patients was 17.9 (12-20, median 19) years. There were five men (45%) and six women (55%). In all cases, the tumor was unilateral. In five (45%) cases the tumor affected the right eye and in six (55%) cases the left eye. Eight (72%) patients were treated with local resection. Among these, eight patients, in two (18%) with iris or ciliary body melanoma we used adjuvant Ru-106 episcleral plaque brachytherapy (EPB). In two (18%) cases of choroidal melanoma, we performed I-125 EPB: one case ended with regression of the tumor, while the second did not respond to EPB and we had to enucleate the eye. In one (9%) case we performed enucleation as the primary treatment. The mean follow-up was 61.4 months, ranging 30-125 months. All those patients are still alive and no metastases were detected. CONCLUSIONS Uveal melanoma is a rare malignancy in children and teenagers. In the present series, it occurred in the iris in more than 50% of cases.

Abstract
PURPOSE To evaluate a kindred with familial uveal and cutaneous melanoma and to identify potential genetic and environmental factors that may predispose individuals to develop uveal melanoma. DESIGN Family-based case report with detailed clinical and genetic evaluation. PARTICIPANTS Ten siblings in a single nuclear family. METHODS Evaluation of a large sibship via family history, complete eye and skin examinations, environmental risk factor questionnaire, and genetic testing, as well as a MEDLINE search of familial uveal melanoma kindreds. MAIN OUTCOME MEASURES Cutaneous and ocular nevi, benign and malignant neoplasms of skin and other sites, brief skin cancer risk assessment tool risk classification for cutaneous melanoma, DNA sequencing of p16INK4a and p14ARF genes, and citations on familial uveal melanoma. RESULTS The proband and his mother had uveal melanoma, 3 cutaneous melanomas occurred among 2 siblings, and 2 other siblings had basal cell carcinomas. No germline mutations were detected in the melanoma-associated tumor suppressor genes p16INK4a and p14ARF. Seven out of 10 siblings had a history of cutaneous and/or ocular nevi. Of the 3 subjects without nevi, 2 had histories of eye or skin malignancies (1 uveal melanoma, 1 basal cell carcinoma). Three of the 10 siblings had relevant ocular findings (2 choroidal nevi, 1 uveal melanoma). Six were also found to be in the "high-risk" classification for cutaneous malignancies based on scores from a previously validated risk assessment tool. This family, combined with the 91 previously reported familial uveal melanoma kindreds, brings to 92 the total number thus far recorded. CONCLUSIONS Our results strengthen the association between uveal melanoma, atypical nevi, and cutaneous melanoma. This relationship supports the recommendation that individuals with a personal or family history of uveal melanoma, particularly in combination with atypical nevi, should be regularly screened for uveal and cutaneous melanoma.

Abstract
INTRODUCTION We conducted a retrospective study on the clinical factors influencing the local and general prognosis of patients treated for uveal melanoma with a preliminary analysis of the prognostic value of monosomy 3. PATIENTS and method: The patients sent to Curie Institute for uveal melanoma have a complete initial clinical evaluation, conservative management by radiotherapy or enucleation, and local and general long-term follow-up. Over the last 5 years, the status of chromosome 3 has been assessed by FISH in the tumors of enucleated patients. Findings concerning the initial workup, treatment, and follow-up are recorded prospectively. We conducted a retrospective study with multivariate analysis of the clinical factors influencing local recurrence, ocular conservation metastasis, and survival and studied the effect of monosomy 3. RESULTS A total of 2241 patients were registered with a median follow-up of 72 months. Of these patients, 92.8% had conservative management with iodine 125 brachytherapy or proton beam therapy and 7.2% of the patients had enucleation (n=160). Tumors from 120 patients were studied for the status of chromosome 3 by FISH. The overall survival rate was 76.3% and the metastatic rate was 19.5%. The clinical factors influencing survival were the size and location of the tumor, age of the patient, gender, and initial treatment. The factors influencing the metastatic risk were the same plus retinal detachment and local recurrence. Monosomy 3 was a significant risk factor for metastatic disease. DISCUSSION This study found the usual risk factors with the difference that location on the equator seems to be of worse prognosis than ciliary body involvement for survival and metastasis. In addition, the initial retinal detachment appears to be a risk factor for local recurrence and metastasis. At present, the evaluation of chromosome 3 is available for enucleated tumors but it could probably be done on needle biopsy performed during conservative management as well. CONCLUSION This study confirms previous results on the prognostic factors of uveal melanoma and on the value of monosomy 3. The increasingly precise identification of a group of high-risk patients should allow us to propose adjuvant therapy and to adapt follow-up.

Abstract
No systematic population-based studies have been conducted on familial eye cancers. Reliable data on familial risks are important for clinical counselling and cancer genetics. The current analysis was based on the nation-wide Swedish Family-Cancer Database on 10.5 million individuals, containing families with parents and offspring. Cancer data were retrieved from the Swedish Cancer Registry from the years 1958 to 2002, including 3636 patients with any type of eye cancer. Familial risk for offspring was defined using the standardized incidence ratio (SIR), adjusted for many variables. Ocular melanoma was detected in two parent-offspring pairs, but the SIR of 3.90 was not significant. Parental upper aerodigestive tract (2.05), left-sided colon (1.83) and male non-medullary thyroid (6.98) cancers showed an association with ocular melanoma, albeit some with a borderline significance. The SIR for leukaemia was increased when parents were diagnosed with eye melanoma. There was no evidence for the association of ocular melanoma with cutaneous melanoma. The SIR for ocular melanoma was 1.76 when a sister was diagnosed with breast cancer, but there was no increase when a mother was diagnosed with breast cancer. When both a child and the parent presented with retinoblastoma, the SIR was 900. The parents of children with retinoblastoma had an excess of small intestinal and rectal cancers and Hodgkin's disease. The present findings were based on a limited number of cases, but they display a complex and heterogeneous pattern of familial associations in ocular melanoma, including an association with breast cancer through a putative recessive mechanism.

Abstract
Uveal melanoma is the most frequent intraocular cancer. The recent development of new technologies such as microsatellite analysis and comparative genomic hybridization have elucidated both the cytogenetics and the natural history of this disease. Fifty to 60% of uveal melanomas are linked to monosomy 3, which appears as an early and determinant event in tumor progression. Tumors with this anomaly have a very poor prognosis. Recent work suggests that this category of uveal melanomas represents a distinct pathological entity from that associated with normal disomy 3. Chromosome 6 aberrations probably make up a second entry point into the process of carcinogenesis, while gains in 8q seem to appear later in the natural history of uveal melanoma because of their higher frequency in larger tumors. Progress in genome analysis has identified regions in chromosomes 3, 6, and 8 as those most probably involved in tumorigenesis. It is to be hoped that this will soon lead to the discovery of the genes responsible.
